What the AI looks for in Automotive Replacement Auxiliary Electric Cooling Fan Kits

Pusher vs. puller: A puller fan mounts on the engine side of the radiator and a pusher mounts in front of the condenser. Buy the configuration your space allows, or a reversible fan. Puller fans are generally more efficient. Pushers are used when there is no room behind the radiator.
Size vs. core coverage: Choose the largest fan or dual-fan setup that fits within the core dimensions, and measure available depth including the shroud. Airflow across the whole core matters more than peak airflow through a small spot.
Current draw and wiring: Use a relay and a fuse sized to the fan's rated amp draw. Do not run the fan through a switch or the existing wiring alone. High-current fans overheat undersized wiring and switches.
Activation control: Set the fan-on temperature slightly above the thermostat opening temperature. If the fan is for A/C, also trigger it from the A/C clutch circuit. Otherwise the fan fights the thermostat, or the A/C loses condenser airflow at idle.
Mounting method: Prefer bracket or shroud mounting over the plastic ties that pass through the core where possible. Through-core ties can abrade the radiator or condenser tubes.

Kits that come without a relay or a fused wiring harness.
Fans whose amp draw exceeds what your alternator can handle at idle.
Running an auxiliary fan with no temperature or A/C trigger, either always on or manual only.
